Abstract

In the BUILD Report 2023:21 Greenhouse gas emissions of new buildings, the analytical basis for establishing potential limit values for greenhouse gas emissions from the new buildings is presented. The report develops a method for establishing limit values based on representative case samples for typical new buildings in Denmark, in which GHG emissions over their life cycle have been calculated according to the current legislation in the Building Regulation (BR18), however, with new environmental data on materials and new emissions factors for the energy grid. Based on the method, potential limit values are proposed which ensures that 1/3 of new buildings from 2025 must perform better than currently. Potential reductions of GHG emissions of implemented new limits estimated.
